The behaviour of Lawesson's reagent and dialkylaminophosphines towards dicyanomethylene derivatives of xanthone and fluorenone
Abdel-Malek, Hoda A.
, p. 457 - 464 (2003)
Lawesson's reagent 1 reacts with xanthen-9-ylidenemalono-nitrile 3 to give adducts 5a, 6a and 7, respectively. In case of the reaction of fluoren-9-ylidenemalononitrile 4 with 1, only 3-amino-2-fluoren-9-ylidene-3- thioxopropanenitrile 5b is obtained toge
Reactions of nitroxides with sulfur-containing compounds, part IV: Synthesis of novel nitroxide (thio)ureas
Zakrzewski, Jerzy,Krawczyk, Maria
, p. 393 - 401 (2007/10/03)
The reactions of 4-isothiocyanato-2,2, 6,6-tetramethylpiperidine-1-oxyl 2 and 4-isocyanato-2,2,6,6-tetramethylpiperidine-1-oxyl 3 with selected amines and lower alcohols give the corresponding novel thioureas 4, ureas 5, thiocarbamates 6, and carbamates 7, all bearing the nitroxyl moiety. The characteristic features of EI mass spectra of (thio)ureas 4 and 5 are described. Some of the synthesized thioureas 4, ureas 5, thiocarbamates 6, and carbamates 7 are moderately or weakly active against pathogenic fungi.

p-Benzoquinonediimines (IIIa-c) react with 2,4-bis-(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (I) to produce compounds Va-c. p-Naphthoquinonediimines (IVa,b) react with the same reagent to produce compounds Xa,b. Key words: p-Benzoquinonedibenzenesulfonimine IIIa; p-benzoquinonedimethanesulfonimine IIIb; p-benzoquinonedibenzimide IIIc; 1,4-naphthoquinonedibenzenesulfonimine IVa; 1,4-naphthoquinonedimethanesulfonimine IVb; 2,4-bis-(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson Reagent) I; 1,3,2-benzoazathiaphophole-2-sulfides (V); 1,3,2-naphthoazathiaphophole-2-sulfides X).
